Description
大容量儲存系統不斷提供增加的儲存容量以滿足使用者需求。照片與電影儲存以及照片與電影分享係激發對越來越大的儲存系統需求之增長的應用實例。Mass storage systems continue to provide increased storage capacity to meet user needs. Photo and movie storage, as well as photo and film sharing, are examples of applications that are driving the growing demand for storage systems.
對這些日益增加的需求的一個解決方法是使用多重廉價磁碟的陣列。這些陣列可按可提供冗餘錯誤恢復而沒有任何資料損失的方式組態。這些陣列也可被組態成經由允許資料同時被讀或寫到多重磁碟機而增加讀寫性能。這些陣列還可被組態成允許「熱插拔」，其允許一故障磁碟被替換而不中斷該陣列的儲存服務。多重磁碟儲存系統通常利用一控制器，該控制器讓使用者或主機系統避開管理該儲存陣列的細節。該控制器可使該儲存陣列呈現為一或多個磁碟機(或磁碟區)。這是不顧以下事實而實現的，即一特定磁碟區的資料(或冗餘資料)可跨多重磁碟機分佈。One solution to these increasing demands is to use an array of multiple inexpensive disks. These arrays can be configured in a way that provides redundant error recovery without any data loss. These arrays can also be configured to increase read and write performance by allowing data to be read or written to multiple drives simultaneously. These arrays can also be configured to allow "hot plugging" which allows a failed disk to be replaced without interrupting the array's storage service. Multiple disk storage systems typically utilize a controller that allows the user or host system to circumvent the details of managing the storage array. The controller can cause the storage array to be presented as one or more disk drives (or disk regions). This is achieved regardless of the fact that the data (or redundant data) of a particular disk area can be distributed across multiple disks.
為促進這些多重磁碟儲存系統的發展與利用，已制定幾個規範。這些規範由儲存橋接聯盟工作組公司(Storage Bridge Bay Working Group,Inc.)頒佈。特定言之，2008年1月28日，該儲存橋接聯盟工作組公司已經頒佈儲存橋接聯盟(SSB)規範2.0版本，可在www.ssbwg.org獲得。該規範目的是在一儲存外殼與對系統提供功能的電子卡之間定義共同的機械、電氣和內部介面。該SSB規範的最終目的是允許多重不同控制器被用在一單件式、符合標準的機殼中以改變儲存陣列的「個性」。Several specifications have been developed to facilitate the development and utilization of these multiple disk storage systems. These specifications were issued by the Storage Bridge Bay Working Group, Inc. Specifically, on January 28, 2008, the Storage Bridge Alliance Working Group Corporation has issued version 2.0 of the Storage Bridge Alliance (SSB) specification, available at www.ssbwg.org. The purpose of this specification is to define a common mechanical, electrical, and internal interface between a storage enclosure and an electronic card that provides functionality to the system. The ultimate goal of the SSB specification is to allow multiple different controllers to be used in a single-piece, standards-compliant enclosure to change the "personality" of the storage array.
本發明的一實施例因此可包括一儲存系統外殼，其包括：一中平面，其從一耦合到該中平面的控制器接收一第一驅動狀態信號和一第二驅動狀態信號，該第一驅動狀態信號和該第二驅動狀態信號是與一耦合到該中平面的第一驅動器相關，該第一驅動狀態信號指示一與該第一驅動器相關的故障狀態，該第二驅動狀態信號指示一動作被允許；一驅動電源控制器，其從該第一驅動器移除電源以回應該第一驅動狀態信號和該第二驅動狀態信號。An embodiment of the invention may thus include a storage system housing including: a midplane that receives a first drive state signal and a second drive state signal from a controller coupled to the midplane, the first The drive status signal and the second drive status signal are associated with a first driver coupled to the midplane, the first drive status signal indicating a fault condition associated with the first driver, the second drive status signal indicating a An action is allowed; a drive power controller that removes power from the first driver to respond to the first drive state signal and the second drive state signal.
本發明的一實施例可進一步包括一種控制一儲存器件電源的方法，其包括：從一控制器接收一第一驅動狀態信號；從該控制器接收一第二驅動狀態信號；基於該第一驅動狀態信號，控制一與對該儲存器件所需之一動作相關的第一發光指示器；基於該第二驅動狀態信號，控制一與對該儲存器件所允許之一動作相關的第二發光指示器；基於該第一驅動狀態信號和該第二驅動狀態信號，提供電源至該儲存器件。An embodiment of the present invention may further include a method of controlling a power of a storage device, comprising: receiving a first driving state signal from a controller; receiving a second driving state signal from the controller; based on the first driving a status signal controlling a first illuminating indicator associated with an action required for the storage device; controlling a second illuminating indicator associated with an action permitted by the storage device based on the second driving status signal Providing power to the storage device based on the first drive state signal and the second drive state signal.
圖1是一儲存系統的框圖。在圖1中，儲存系統100包括：控制器110、控制器111、儲存器件120、儲存器件121、中平面130、發光器件140-143、電源控制器150、電源控制器151、驅動狀態信號160-163以及發光器件驅動器170-171。控制器110-111被有效地耦合到中平面130。儲存器件120-121被有效地耦合到中平面130。因此，控制器110-111可經由中平面130有效地與儲存器件120-121連接或交換資訊。控制器110-111可有效地與耦合到該儲存系統100的其他器件(未顯示)連接或交換該資訊。儲存系統100可包括額外的控制器。儲存系統100可包括額外的儲存器件。然而，為了簡潔起見，圖1已經省略此等器件。Figure 1 is a block diagram of a storage system. In FIG. 1, the storage system 100 includes a controller 110, a controller 111, a storage device 120, a storage device 121, a midplane 130, light emitting devices 140-143, a power controller 150, a power controller 151, and a drive status signal 160. - 163 and light emitting device drivers 170-171. Controllers 110-111 are operatively coupled to midplane 130. The storage devices 120-121 are effectively coupled to the midplane 130. Thus, the controllers 110-111 can effectively interface or exchange information with the storage devices 120-121 via the midplane 130. Controllers 110-111 can effectively connect or exchange this information with other devices (not shown) coupled to the storage system 100. Storage system 100 can include additional controllers. The storage system 100 can include additional storage devices. However, for the sake of brevity, Figure 1 has omitted such devices.
儲存系統100可為或包括一符合該SBB規範的系統。因此，控制器110-111可為或包括與下列相容或藉由下列描述的控制器，例如無限寬頻(InfiniBand)、集束磁碟(Just a Bunch Of Disks)或驅動機盒(JBOD)、廉價磁碟冗餘陣列(RAID)、網路附接儲存器(NAS)、儲存陣列網路(SAN)、iSCSI SAN或虛擬磁帶庫(VTL)。因此，儲存器件120-121可為或包括硬碟機。儲存器件120-121可為或包括其他類型的驅動器，如固態磁碟機、磁帶驅動器和唯讀記憶體(ROM)驅動器。其他類型的儲存器件是可以的。Storage system 100 can be or include a system that conforms to the SBB specifications. Thus, the controllers 110-111 can be or include controllers that are compatible with or described below, such as InfiniBand, Just a Bunch Of Disks, or JBOD, inexpensive Redundant Array of Disks (RAID), Network Attached Storage (NAS), Storage Array Network (SAN), iSCSI SAN, or Virtual Tape Library (VTL). Thus, storage devices 120-121 can be or include a hard disk drive. The storage devices 120-121 can be or include other types of drives, such as solid state drives, tape drives, and read only memory (ROM) drives. Other types of storage devices are possible.
發光器件140-143可為或包括對儲存系統100的使用者是可見的指示器。例如，發光器件140-143可為或包括一燈泡或發光二極體(LED)，其對使用者提供一關於儲存系統100的一或多個元件的狀態的指示或資訊。在一實施例中，發光器件140-143可藉由發光器件驅動器170-171控制。然而，應明白發光器件驅動器170-171是可選的以及發光器件140-143可直接由控制器110或111控制。Light emitting devices 140-143 can be or include indicators that are visible to a user of storage system 100. For example, light emitting devices 140-143 can be or include a light bulb or light emitting diode (LED) that provides an indication or information to a user regarding the status of one or more components of storage system 100. In an embodiment, the light emitting devices 140-143 can be controlled by the light emitting device drivers 170-171. However, it should be understood that the light emitting device drivers 170-171 are optional and that the light emitting devices 140-143 can be directly controlled by the controller 110 or 111.
在一實施例中，控制器110可供應驅動狀態信號160至中平面130。驅動狀態信號160可與在儲存器件120上所需的一動作相關。驅動狀態信號160可由中平面130轉送至發光器件驅動器170以控制發光器件140。發光器件140的狀態(即，「開啟」或「關閉」)在儲存系統100的外部可以是可見的。發光器件140的狀態可指示使用者在儲存器件120上需要一動作。例如，當發光器件140開啟時，其可指示使用者需要一維修動作。在一實施例中，驅動狀態信號160可對應於在SBB規範中定義的一低速驅動狀態信號。特定言之，驅動狀態信號160可對應於在SBB規範中定義的一Drive_X_Fault_L信號，其中X是對應儲存器件120的數目。In an embodiment, controller 110 may supply drive status signal 160 to midplane 130. The drive status signal 160 can be associated with an action required on the storage device 120. Drive state signal 160 may be forwarded by midplane 130 to light emitting device driver 170 to control light emitting device 140. The state of the light emitting device 140 (i.e., "on" or "off") may be visible outside of the storage system 100. The state of the light emitting device 140 may indicate that the user needs an action on the storage device 120. For example, when the light emitting device 140 is turned on, it can indicate that the user needs a maintenance action. In an embodiment, the drive status signal 160 may correspond to a low speed drive status signal as defined in the SBB specification. In particular, the drive status signal 160 may correspond to a Drive_X_Fault_L signal as defined in the SBB specification, where X is the number of corresponding storage devices 120.
控制器110可供應驅動狀態信號161至中平面130。驅動狀態信號161可與在儲存器件120上所允許的一動作相關。驅動狀態信號161可由中平面130轉送至發光器件驅動器170以控制發光器件141。發光器件141的狀態在儲存系統100的外部可以是可見的。發光器件141的狀態可指示使用者在儲存器件120上允許一動作。例如，當發光器件141開啟時，其可指示使用者允許一特定維修動作。該維修動作可包含替換或「熱插拔」儲存器件120。在一實施例中，驅動狀態信號161可對應於在SBB規範中定義的一低速驅動狀態信號。特定言之，驅動狀態信號161可對應於在該SBB規範中定義的一Drive_X_GPO_L信號，其中X是對應儲存器件120的數目。The controller 110 can supply the drive status signal 161 to the midplane 130. The drive status signal 161 can be associated with an action allowed on the storage device 120. The drive status signal 161 can be forwarded by the midplane 130 to the light emitting device driver 170 to control the light emitting device 141. The state of the light emitting device 141 may be visible outside of the storage system 100. The state of the light emitting device 141 may instruct the user to allow an action on the storage device 120. For example, when the light emitting device 141 is turned on, it can instruct the user to allow a particular repair action. This repair action may include replacing or "hot plugging" the storage device 120. In an embodiment, the drive status signal 161 may correspond to a low speed drive status signal as defined in the SBB specification. In particular, the drive status signal 161 may correspond to a Drive_X_GPO_L signal as defined in the SBB specification, where X is the number of corresponding storage devices 120.
控制器110還可供應驅動狀態信號162-163至中平面130。驅動狀態信號162-163可與儲存器件121相關。驅動狀態信號162和163可分別對應於在儲存器件121上所需的一維修動作和所允許的維修動作。驅動狀態信號162和163可由中平面130提供至發光器件驅動器171以分別控制發光器件142和143。發光器件142和143的狀態在儲存系統100的外部可以是可見的。發光器件142和143的狀態可指示使用者在儲存器件121上需要或允許一動作。驅動狀態信號162和163可對應於在SBB規範中定義的低速驅動狀態信號。特定言之，驅動狀態信號162和163可分別對應於在SBB規範中定義的一Drive_X_Fault_L和一Drive_X_GPO_L信號，其中X是對應儲存器件121的數目。Controller 110 may also supply drive status signals 162-163 to midplane 130. Drive status signals 162-163 may be associated with storage device 121. Drive status signals 162 and 163 may correspond to a desired maintenance action and an allowed maintenance action on storage device 121, respectively. Drive state signals 162 and 163 may be provided by midplane 130 to light emitting device driver 171 to control light emitting devices 142 and 143, respectively. The states of the light emitting devices 142 and 143 may be visible outside of the storage system 100. The state of the light emitting devices 142 and 143 may indicate that the user needs or allows an action on the storage device 121. Drive state signals 162 and 163 may correspond to low speed drive state signals as defined in the SBB specification. In particular, drive status signals 162 and 163 may correspond to a Drive_X_Fault_L and a Drive_X_GPO_L signal, respectively, as defined in the SBB specification, where X is the number of corresponding storage devices 121.
在一實施例中，控制器111也可控制驅動狀態信號160-163。在這種情況下，中平面130可邏輯組合從控制器110-111(以及其他控制器，未顯示)接收的驅動狀態信號160-163。例如，中平面130可以「線或」方式連接從控制器110接收的驅動狀態信號160-163和從控制器111接收的驅動狀態信號以使其等進行邏輯或。應明白邏輯組合從多重控制器110-111接收的多重驅動狀態信號160-163的其他方式是可以的。In an embodiment, controller 111 can also control drive status signals 160-163. In this case, midplane 130 may logically combine drive state signals 160-163 received from controllers 110-111 (and other controllers, not shown). For example, midplane 130 may connect drive state signals 160-163 received from controller 110 and drive status signals received from controller 111 in a "wire-by-wire" manner to cause them to logically OR. It should be appreciated that other ways of logically combining the multiple drive status signals 160-163 received from the multi-controllers 110-111 are possible.
中平面130提供電源至儲存器件120。中平面130提供電源至儲存器件121。在一實施例中，中平面130包含電源控制器150和電源控制器151。電源控制器150被組態成控制(即，提供或拒絕提供)電源至儲存器件120。電源控制151器被組態成控制電源至儲存器件121。中平面130可包括額外的電源控制器(未顯示)，其等控制電源至額外的儲存器件(未顯示)。然而，為簡潔起見，圖1已經省略此等器件。電源控制器150-151可包括一開關器件，其可連接和斷開供應至儲存器件120-121的電源。例如，電源控制器150或151可包括一電源MOSFET、雙極型電晶體、繼電器或其他可分別選擇性地提供和拒絕提供電源至儲存器件120和121的開關器件。The midplane 130 provides power to the storage device 120. The midplane 130 provides power to the storage device 121. In an embodiment, the midplane 130 includes a power controller 150 and a power controller 151. The power controller 150 is configured to control (ie, provide or deny) power to the storage device 120. The power control 151 is configured to control the power supply to the storage device 121. The midplane 130 may include an additional power controller (not shown) that controls the power to an additional storage device (not shown). However, for the sake of brevity, Figure 1 has omitted such devices. The power controllers 150-151 can include a switching device that can connect and disconnect power supplies to the storage devices 120-121. For example, power controller 150 or 151 can include a power MOSFET, a bipolar transistor, a relay, or other switching device that can selectively provide and deny supply of power to storage devices 120 and 121, respectively.
在一實施例中，電源控制器150接收驅動狀態信號160和161。驅動狀態信號160-161可由電源控制器150用於控制至儲存器件120的電源。例如，當驅動狀態信號160和161均為有效時，則電源控制器150可拒絕提供(或移除)至儲存器件120的電源。當驅動狀態信號160或161任一者是非有效時，則儲存器件120由電源控制器150供應電源。因此，當發光器件140和141均為開啟時，至儲存器件120的電源是關閉的。電源控制器151在驅動狀態信號162-163的控制下可以一類似的方式起作用。同樣地，當發光器件142和143均為開啟時，至儲存器件121的電源是關閉的。In an embodiment, power controller 150 receives drive status signals 160 and 161. Drive state signals 160-161 may be used by power controller 150 to control power to storage device 120. For example, when drive state signals 160 and 161 are both active, power controller 150 may reject the power provided to (or removed from) storage device 120. When either of the drive status signals 160 or 161 is inactive, the storage device 120 is powered by the power supply controller 150. Therefore, when the light emitting devices 140 and 141 are both turned on, the power to the storage device 120 is turned off. The power controller 151 can function in a similar manner under the control of the drive status signals 162-163. Likewise, when the light emitting devices 142 and 143 are both turned on, the power to the storage device 121 is turned off.
在一實施例中，控制器110或控制器111可使用驅動狀態信號160-163的狀態重設儲存器件120-121。例如，控制器110可用在非有效狀態的驅動狀態信號160或161作業。因此，電源控制器150將供應電源至儲存器件120。控制器110然後可將驅動狀態信號160和161設定成一有效狀態。這使電源控制器150移除至儲存器件120的電源。在一段足以使儲存器件120重設的時間之後，控制器110可將驅動狀態信號160或161之至少一個設定成一非有效狀態。這使電源控制器150恢復至儲存器件120的電源。電源的中斷使儲存器件120自己重設或重啟。In an embodiment, controller 110 or controller 111 may reset storage devices 120-121 using the status of drive status signals 160-163. For example, controller 110 can be operated with drive status signal 160 or 161 in an inactive state. Therefore, the power controller 150 will supply power to the storage device 120. Controller 110 can then set drive state signals 160 and 161 to an active state. This causes the power controller 150 to remove power to the storage device 120. After a period of time sufficient to reset the storage device 120, the controller 110 may set at least one of the drive status signals 160 or 161 to an inactive state. This causes the power controller 150 to restore power to the storage device 120. The interruption of the power supply causes the storage device 120 to reset or restart itself.
圖2是一種控制一儲存器件電源的方法的流程圖。圖2中所說明的步驟可由儲存系統100的一或多個元件實施。2 is a flow chart of a method of controlling the power of a storage device. The steps illustrated in FIG. 2 may be implemented by one or more components of storage system 100.
一第一驅動狀態信號被從一控制器接收(202)。例如，中平面130可從控制器110接收驅動狀態信號160。一第二驅動狀態信號被從該控制器接收(204)。例如，中平面130可從控制器110接收驅動狀態信號161。A first drive status signal is received (202) from a controller. For example, midplane 130 may receive drive status signal 160 from controller 110. A second drive status signal is received (204) from the controller. For example, midplane 130 may receive drive status signal 161 from controller 110.
基於該第一驅動狀態信號，一與在一儲存器件上所需的一動作相關的第一發光指示器被控制(206)。例如，發光器件140可與在儲存器件120上所需的一維修動作相關。發光器件140可由中平面130控制以回應從控制器110接收的該第一驅動狀態信號。Based on the first drive state signal, a first illumination indicator associated with an action required on a storage device is controlled (206). For example, light emitting device 140 can be associated with a maintenance action required on storage device 120. Light emitting device 140 can be controlled by midplane 130 in response to the first drive state signal received from controller 110.
基於該第二驅動狀態信號，一與在一儲存器件上所需的一動作相關的第二發光指示器被控制(208)。例如，發光器件141可與在儲存器件120上所允許的一維修動作相關。發光器件141可由中平面130控制以回應從控制器110接收的該第二驅動狀態信號。Based on the second drive state signal, a second illumination indicator associated with an action required on a storage device is controlled (208). For example, the light emitting device 141 can be associated with a maintenance action that is permitted on the storage device 120. Light emitting device 141 can be controlled by midplane 130 in response to the second drive state signal received from controller 110.
基於該第一驅動狀態信號和該第二驅動狀態信號，電源被提供至該儲存器件(210)。例如，為回應該第一驅動狀態信號及該第二驅動狀態信號是非有效的，中平面130可使用電源控制器150提供電源至儲存器件120。如果該第一驅動狀態信號和該第二驅動狀態信號均為有效，則中平面130可使用電源控制器150拒絕提供或移除至儲存器件120的電源。Based on the first drive state signal and the second drive state signal, a power source is provided to the storage device (210). For example, to return the first drive state signal and the second drive state signal to be inactive, the midplane 130 can provide power to the storage device 120 using the power controller 150. If both the first drive state signal and the second drive state signal are active, the midplane 130 may reject the power supply to the storage device 120 using the power controller 150.
圖3是一種對一儲存器件提供和拒絕提供電源的方法的流程圖。圖3中所說明的步驟可由儲存系統100的一或多個元件實施。3 is a flow chart of a method of providing and denying power to a storage device. The steps illustrated in FIG. 3 may be implemented by one or more components of storage system 100.
一在有效狀態中的第一驅動狀態信號被接收(302)。例如，中平面130可從控制器110接收在有效狀態中的驅動狀態信號160。一在有效狀態中的第二驅動狀態信號被接收(304)。例如，中平面130可從控制器110接收在有效狀態中的驅動狀態信號161。A first drive state signal in the active state is received (302). For example, midplane 130 may receive drive state signal 160 in an active state from controller 110. A second drive state signal in the active state is received (304). For example, midplane 130 may receive drive state signal 161 in an active state from controller 110.
為回應該第一驅動狀態信號和該第二驅動狀態信號均為在有效狀態中，一開關器件被控制以拒絕提供電源至一儲存器件(306)。例如，為回應驅動狀態信號160和驅動狀態信號161是在有效狀態中，中平面130可使用電源控制器150控制一開關器件以拒絕提供電源至儲存器件120。In response to the fact that both the first drive state signal and the second drive state signal are active, a switching device is controlled to reject supply of power to a storage device (306). For example, in response to the drive state signal 160 and the drive state signal 161 being in an active state, the midplane 130 can use the power controller 150 to control a switching device to deny the supply of power to the storage device 120.
在非有效狀態中的該第一或第二驅動狀態信號(或兩者)被接收(308)。例如，在非有效狀態中的驅動狀態信號160或161任一者或兩者都可由中平面130從控制器110接收。為回應該第一驅動狀態信號或該第二驅動狀態信號是在非有效狀態中，控制該開關器件以提供電源至該儲存器件(310)。例如，為回應驅動狀態信號160或驅動狀態信號161(或兩者)是在非有效狀態中，中平面130可使用電源控制器150控制一開關器件以提供電源至儲存器件120。The first or second drive state signal (or both) in the inactive state is received (308). For example, either or both of the drive status signals 160 or 161 in the inactive state may be received by the controller 110 from the midplane 130. In response to the first drive state signal or the second drive state signal being in an inactive state, the switching device is controlled to provide power to the storage device (310). For example, in response to drive state signal 160 or drive state signal 161 (or both) being in an inactive state, midplane 130 may use power controller 150 to control a switching device to provide power to storage device 120.
